Hi @Psb1,
Welcome to our Community Help Forum 🙂
Sorry to hear that you are having these problems with your landline, that is not ideal at all. I would like to take a look at your account to run some diagnostics and see if we need to send an engineer. I shall send you a private message now to obtain the details required. Please look out for the purple envelope in the top right corner and get back to me when you can.
Best wishes,
Serena
